摘要
数控分频器的输出信号频率为输入数据的函数。用传统的方法设计,其设计过程和电路都比较复杂,且设计成果的可修改性和可移植性都较差。基于VHDL的数控分频器设计,整个过程简单、快捷,极易修改,可移植性强。他可利用并行预置数的加法计数器和减法计数器实现。广泛应用于电子仪器、乐器等数字电子系统中。
The output signal of the numerical control frequency division machine is the function of the input data. Both the design process and the circuit are very complicated if designed by the conventional method. Moreover,the modification and the replantation of the design fruits are very bad. The design process of the numerical control frequency division machine is simple, shortcut,simply modified and replanted. It can realize by using the adder and the subtracter of parallel initialized data. It is widely applied in the electron instrument and musical instrument of the electron system.
